Recently I laid a drain for a toilet pan with a 100 mm riser through a concrete slab I have the riser 60 mm from the wall I know that's too close but is there any other options I can do before I smash up the slab any joints I can use??

Let's see if I've got this straight.
You roughed in a toiler 60mm off the wall that should be 304.8mm to center off the wall? Sorry but there is no "whiz-bang" fix for this,
The slab will have to be opened and the toilet raiser positioned correctly.
Good luck, Tom
